Still it can't handle the case of:
ubyte[3] x = [1, 2, 3];
Making the parameter variadic seems to do the trick:
----
import std.traits: Unqual;
Unqual!T[n] s(T, size_t n)(T[n] arr ...)
{
return arr[];
/* With indirections, dmd would complain about an
escaping reference. Slicing shuts it up. */
}
void main()
{
auto a = s("hello");
static assert(is(typeof(a) == char[5]));
auto x = s!ubyte(1, 2, 3);
static assert(is(typeof(x) == ubyte[3]));
auto y = s(new int, new int);
static assert(is(typeof(y) == int*[2]));
auto z = s(new immutable int, new immutable int);
static assert(is(typeof(z) == immutable(int)*[2]));
}
